description	According to the invention, where the water to be treated is conveyed concurrently with oxygen-containing gas into an upward reactor containing a stationary bed of particles, the support for the bacteria which is employed is particles of a material with a bulk packing density of between 35 and 65 kg/m . The biological reactor(s) or filters (1,1') in series comprise: a sludge-thickening zone (2), at least one device for injecting oxygen-containing gas (3,3'), a filter medium zone (4), a ceiling for retaining the particles (7) and a washing water reserve zone with discharge (9) of the treated effluent. Application to the treatment of effluent water and of water to be made drinkable.
